| Abstract | The authors describe a system for storage and display of QRS morphologies of ventricular arrhythmias from different sources. A substantial reduction of data is achieved by the generation of a so-called morphology atlas, containing only representative QRS complexes. An algorithm is described that groups the different morphologies into families. The hardware configuration of the system consists of a digitizer (resolution 0.1 mm), a personal computer, and a printer/plotter. The PC is connected to the central database computer by a serial RS232 line, using the program Kermit for communication. The PC is used as a virtual terminal for the database and controls the digitizer and graphic display. The setup was tested on 24 patients, each with spontaneous monomorphic sustained ventricular tachycardia (VT) late after myocardial infarction, ventricular premature beats (VPBs) recorded on a 5-channel Holter ECG, and (non)-sustained VT induced during programmed electric simulation. The system performed automatic grouping of morphologies rather well in case of (non)-sustained VTs. The correlation threshold of 60% confirmed the diagnoses of three independent observers. In case of VPBs no threshold could be determined.< |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
